Update dspace-parent POM to ONLY build the Unit Test Environment zip when the testEnvironment.xml file exists. This ensures it will NOT be built for the 'binary' release of DSpace.
Turn off Unit testing by default. This ensures that the "binary" release of DSpace won't attempt to run unit tests.
Move the zip/tarball creation assemblies (release.xml & src-release.xml) to [src]/dspace/src/main/assembly/
Also move the DSpace build assembly (assembly.xml) file to that directory as well, to consolidate.
Move the 'distributions' profile (which creates the zip/tarball distributions) to the [src]/dspace/pom.xml.  Minor updates (including enhanced comments) to all three of our Assemblies (assembly.xml, release.xml and src-release.xml), to ensure they all work properly when run from [src]/dspace/src/main/assembly/.  Also minor updates to 'dspace-parent' and 'dspace' POM files.  All these changes now fix issues with 'mvn package -Pdistributions'.
